Now, the ACT Greens say all roadside electoral signs should be banned at next year's territory election.

But they've stopped short of declaring they will not use them if a ban fails to get support.

Under current laws there is no limit to the number of roadside corflutes that can be used in the ACT.

Greens MLA Caroline Le Couteur said they caused visual pollution, cluttering up public spaces.

"For many Canberrans, roadside electoral signs are supremely annoying, and distracting. Once the election is over, we can only assume that most of these end up going straight into landfill," she said.

"If you're driving along and there are dozens of election signs along the roads, it's both annoying and distracting for drivers.

"Many of the signs are largely policy-free - it's not as though they are informative. It's time to get rid of these annoying electoral signs - they're a huge turn off for the community and are a huge waste of plastic."

It comes after thousands of corflutes lined Canberra streets sparking during the 2016 election campaign, sparking complaints to the electoral commission.

It even led to a corflute whacking party, organised by the Like Canberra party.

At the federal election in May, the Greens did not use roadside electoral signage - instead, corflutes were displayed in private yards or held by volunteers for limited times.

But they haven't yet committed to doing the same for the upcoming territory election.

Chief Minister Andrew Barr said a select committee inquiry into the 2016 election found restricting corflutes from arterial roads would result in an influx in a compact area.

"The committee also noted that the move would significantly limit the opportunity for minor or independent parties to promote themselves," he said.

"The Government is prioritising the implementation of the recommendations that were agreed to in our response to the select committee's report, including the ban on property developer donations to any party represented in the ACT Legislative Assembly.

"This is also an item in the Parliamentary Agreement between ACT Labor and the Greens and we are looking forward to their support for the passing of this legislation as soon as possible."
